sudo: unable to resolve host ubuntu
wget: unable to resolve host address `samba.org'
wget: unable to resolve host address `bitcoincore.org'
Two questions:
1. Can you specify which "first command" you are running?
This one, the first in the "Build Bitcoin Core..." section:
./bin/gbuild --commit bitcoin=v${VERSION} ../bitcoin/contrib/gitian-descriptors/gitian-linux.yml
2.Can you ping those hosts from your server?
e.g.
ping samba.org
ping bitcoincore.org
:-)
From the server:
ubuntu - no
samba.org - yes
bitcoincore.org - yes
From the vm gitian made to do the build:
ubuntu - no
samba.org - no
bitcoincore.org -no
FYI, ubuntu is the hostname (at least it should be) of the vm that gitian created to do the building.
Also, when I ping from the VM it gives this message for each ping (but with different doman):
ping: unknown host bitcoincore.org
